Graphene-Paper Based Electrochemical Sensors

Abstract

Graphene paper as a new form of graphene-supported nanomaterials has received worldwide attention since its first report in 2007. Due to their high flexibility, lightweight and good electrical conductivity, graphene papers have demonstrated the promising potential for crucial applications in electrochemical sensors and energy technologies among others. In this chapter, we present some examples to overview recent advances in the research and development of two-dimensional (2D) graphene papers as new materials for electrochemical sensors. The chapter covers the design, fabrication, functionalization and application evaluations of graphene papers. We first summarize the mainstream methods for fabrication of graphene papers/membranes, with the focus on chemical vapour deposition techniques and solution-processing assembly approaches. A large portion of this chapter is then devoted to the highlights of specific functionalization of graphene papers with polymer and nanoscale functional building blocks for electrochemical-sensing purposes. In terms of electrochemical-sensing applications, the emphasis is on enzyme-graphene and nanoparticle-graphene paper-based systems for the detection of glucose. We finally conclude this chapter with brief remarks and outlook.

The potential of paper-based diagnostics to meet the ASSURED criteria

“…6A ), including graphene-based pastes. 66 Simple screen printing techniques are often used to implement electrochemical sensors directly on to paper-based diagnostic tests. Materials development for printed and wearable electrochemical sensors have seen extensive growth, 7 with examples for diagnostic applications ranging from water quality monitoring 67 to cancer detection.…”

Supercapacitor/biofuel cell hybrid device employing biomolecules for energy conversion and charge storage

“…In earlier work, graphene paper (GP) based materials have shown unique properties, i.e. robust mechanical strength, high electrical conductivity, tunable flexibility, low weight and low cost, together with potential applications in biomimetic composites, electrocatalytic sensors and energy storage devices [19][20][21][22][23][24]. Moreover, the fabrication method of GP is scalable and reproducible.…”

Nano-Biosensors for Cancer Diagnostics: Current Status and Future Prospects

“…Graphene is a two-dimensional (2D) nanomaterial, which plays a tremendous role in the electronic and sensor communities due to its improved physical, optical and electrochemical properties [50,51]. Graphene is defined as "a single atom-thick sheet of hexagonally arranged, sp 2 -bonded carbon atoms occurring within a carbon material structure.…”
